About this collection

How waves add, bend and spread. Interference and the double slit, diffraction and the Airy disk, refraction and Snell’s law, the Doppler effect, beats, standing waves, solitons and the Kelvin wake. Unisex pixel-art physics tees and black hoodies in sizes S–5XL, plus stickers, sticker sheets and mugs.

Waves and optics explain rainbows, soap-film colours and why a straw looks bent in water. Each waves and optics design here carries its equation and sources on its product page, so the physics is right.
